I understand your point and it is a valid one
ATP carry a wide selection of choice, including known brands and as a company their service has been spot on and the prices are competitive in my experience...
Allgerman list a couple of choices at very interesting prices, just look at the Lemforder items in the link

If budget is tight buy the cheapest you're comfortable with and accept that they might require changing in a year or sos time.
If budget is not really an issue but value for money is, then I would buy either the Febi, KYB or SKF kit on brand reputation.
Clearly money no object would be GM only
For reference:

At the end of the day, the prices range from £10-75 so bound to find summat to suit in there
